Schoolboy Sports team from the 1920s

A portrait of a school sports team (possibly Cricket although there are only 10) taken sometime in the 1920s.

This is a scan of a black & white picture which was taken of this sports team taken, presumably, after some important win or competition. Because the boys are wearing blazers and whites I would assume this is a cricket team, and possibly the 11th member of the team is the one with the camera. I guess it was quite a long exposure, because a couple of the boys couldn't keep still long enough, and their faces are blurred.
